Ubuntu Security Notice USN-7150-1 resolves python-tornado issues; critical threats addressed to safeguard systems.
Several security issues were fixed in Tornado.

Summary

Several security issues were fixed in Tornado.

Software Description:

- python-tornado: scalable, non-blocking web server and tools

Details:

It was discovered that Tornado incorrectly handled a certain redirect.

A remote attacker could possibly use this issue to redirect a user to an

arbitrary web site and conduct a phishing attack by having the user access

a specially crafted URL. This issue was only addressed in Ubuntu 22.04 LTS,

Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS. Ubuntu 16.04 LTS was previously

addressed in USN-6159-1. (CVE-2023-28370)

It was discovered that Tornado inefficiently handled requests when parsing

cookies. An attacker could possibly use this issue to increase resource

utilization leading to a denial of service. (CVE-2024-52804)
